Video killed the radio star

Thursday, February 26th, 2009

I think I might have mentioned my appearances on BBC radio :-) . Well now I’m producing a video. Actually the video is being made by some final year students from Lincoln University media department and it is part of a series of shorts that the students are producing for Timico.

We are quite lucky to have a top level media facility such as Lincoln University on our doorstep. Their studios are the envy of the BBC- I kid you not.

To date any video I or anyone else at Timico has produced has been pretty much an experimental amateur affair. Now we are doing it properly. Each video has a production team of 4 people. I just need to get a Director’s chair with my name on it and turn up at the right time for makeup.  Of course I’m sure I’ll have a script to learn as well!

Timico is a sponsor of Lincoln University and I am not only looking forward to seeing the videos but presenting a prize at the end of the year. I’ll also show the vids when they are finished sometime in the spring.

Skype Security Italian Style

Monday, February 16th, 2009

The BBC today has reported that Italian crooks are using Skype to avoid detection by police who use traditional wiretapping to monitor phone calls. The Skype signaling and  media path is encrypted which makes it very difficult to tap into. Also because, as a Peer to Peer protocol Skype doesn’t use any centralised servers that might be able to be monitored it adds to the difficulty for law enforcement agencies.

The whole problem is then compounded by the fact that because VoIP/Skype is a very nomadic service, ie you can use it from any internet connection anywhere, it becomes difficult to track the location of a caller.

This is a problem being looked at by Ofcom as part of the process of caller location identification for the emergency services. Currently if someone makes a 999 call from an unknown address, it is difficult to pin down where that call is being made from, at least in a timely manner.

There was a high profile Canadian case where someone dialled for an ambulance and it went to a location three thousand miles from where the call was actually being made from because the address held by the operator was not the address from which the call was being made. 

When a VoIP call is made the details of the call logged by the Internet Telephony Service Provider include the IP address of the originating party. If you are an Internet Service Provider (note the distinction between ITSP and ISP – an ITSP often does not provide the underlying broadband service) you can correlate this IP address with a physical address (ie house number and street).

The problem is that this is a manual process and would likely take hours at best and potentially a couple of days. This is a process that could be automated but it is something that would probalby cost billons to implement universally in the UK.

I’m sure there will be more to say on this subject in 2009. As a final note it is often said that the security forces, aka GCHQ and CIA et al have not cracked the Skype encryption technology. I find this difficult to believe.

BBC iplayer

Tuesday, January 27th, 2009

I caught up with some reading on the BBC  iplayer last night and lifted some interesting facts.  iplayer now has over a million users a day with 1.7 million download requests. The BBC is expecting it’s 300 millionth “play request” anytime now.

During the Olympics usage rose by 40% which is is reflected in the increase in internet usage I reported back in the summer.

What I found amusing was the fact that people only watch a programme for 22 minutes on average which the BBC finds to be a good statistic. Only 35% of viewers watch a 30 minute programme in its entirety. To me this is an indictment of the quality of what is provided for punters to watch and reinforces why I don’t watch TV (Dads Army, rugby internationals and other free to air sports excepted).

For the geeks amongst you the BBC runs the service on 200 servers, has 92% peering which hugely reduces their cost of delivery (though not ours) and peaks at 100TB a day of streaming traffic.

There’s lots more to read in the EBU Technical Review which quotes a number of sources : 2008-q4_iplayer

Child Exploitation and Online Protection (CEOP) Centre In the BBC News

Wednesday, January 21st, 2009

Woke up this morning to another interview on the BBC News that concerns the ISP industry (is there a song there?). This time Jim Gamble, CEO of CEOP was speaking with BBC journalist Angus Crawford regarding the fact that CEOP often gets charged by ISPs when requests for information are made concerning child protection.

Gamble is suggesting that not charging should be the norm and that ISPs should see it as part of their social responsibility. Bit of an emotive subject this one.  I have more than the average number of kids and of course I am interested in protecting them from sick, deranged individuals that roam the wild wild web. I am also a businessman and we have to keep a bit of perspective in play.

Firstly the ISP industry is legally entitled to recover costs under the  Regulation of Investigatory Powers Act (RIPA). Secondly typically when ISPs “cover their costs” all they are doing is recovering a contribution towards their costs rather than the total cost (see penultimate paragraph).  Thirdly the industry gets many thousands of these requests each year.

If there wasn’t a mechanism there to keep these requests down the those actually required, ie by charging for them, the concern is that the floodgates would open and the costs would skyrocket. These costs have to be borne by customers. 

The numbers quoted by CEOP are as follows: 

How much has CEOP paid to Communications Service Providers in each relevant accounting period since setting up in 2006?             

Financial year breakdown:
Financial year 2006/2007                             =       £   37,184.32
Financial year 2007/2008                             =       £   69,717.46
Financial year 2008/2009 (to Dec 08)            =       £   64,604.21

Total                                                        =      £ 171,505.99

How many such requests has CEOPS had for access to information since 2006?   

Financial year breakdown:
Financial Year 2006/2007 Total applications =   1,200
Financial Year 2007/2008 Total applications =   3,600
Financial Year 2008/2009 Total applications =   4,600

Total                                                    =   9,400 

The CEOPs argument is that this money would be better spent on a couple more staff. In fact the charges, if you use the above numbers, work out at around £14 per request which in my mind is exceedingly good value. It certainly doesn’t cover the actual cost of the support.

The ISP industry covers so many areas of interest that it seems to have been in the news a lot recently. Intellectually it is a very interesting space to be and for ISPs brings with it particular challenges: consumers that want to pay very little but demand more for their money and stakeholders fighting their own corners left right and centre contribututing to further pressures on costs. In the B2B space the dynamics are slightly different but nobody can say this is a boring game.

Trefor.net live on the BBC

Monday, January 12th, 2009

For anyone interested in listening in I am appearing on BBC Radio Lincolnshire at 18.30 hours today (Greenwich Mean Time). I am talking about the Data Retention Act which hit the BBC headlines on Friday and which has now been the subject of a couple of posts here and here.

This is not my first appearance on Radio Lincolnshire. However the last one was so long ago I think it was before CDs were invented and I was still playing with the Sinclair Spectrum Computer.

You can catch it on the internet on the BBC’s website at  http://www.bbc.co.uk/lincolnshire/.  I’m on “Drive Time with William Wright”. I’d be interested in any constructive feedback.

Data Retention Act On The BBC News

Friday, January 9th, 2009

I woke up this morning to an article on BBC Radio 4 concerning the forthcoming Data Retention Act (see previous post on this). The article was then carried several times on BBC Radio Lincolnshire, my local station – I’m sure it would have been repeated in all the regions.

The BBC’s slant concerned human rights and seemed to have been triggered by Human rights organisation “Liberty”. What has been happening since my post on the subject is that the tone of the Government’s conversation has moved on towards looking for a centralised database containing records of many different types of communications and not just email and telephony. This might include SMS, IM etc.

Nothing is set in stone here but I have concerns on two fronts. Firstly the technical cost and impracticality of implementing such a database would be huge and criminals would always be able to find ways around appearing on the records. Secondly is very much the human rights angle. 2008 saw a number of high profile examples of the loss personal data of millions of people because of stolen laptops and lost memory sticks.

I want to help the authorities catch criminals and haven’t really been too concerned in the past about their keeping my own personal records on file because I am a good boy. However in the light of last year’s data losses and because it is fundamentally not possible to totally trust the government (which is one of the reasons that democracies have elections) I have changed my tune.

If you want to read the BBC article online you can find it here.

Project Kangaroo Kyboshed

Thursday, December 4th, 2008

The Competition Commission has put the sword to Project Kangaroo. This was a proposed joint venture by the BBC, ITV and Channel 4 for a single online vehicle that would provide each channel’s TV content over the internet. Content was going to be paid for by advertising.

Basically the Commission believes that the venture would reduce competition in the online video market in the uk. The JV may be allowed if it shares its content with other providers and appears to have until 24th December to appeal, presumably informing the Commission of how it would do this.

Personally I can’t understand why people watch the TV anyway. Notwithstanding that, this does point towards a change in business models, in particular for the BBC. It isn’t difficult to envisage a scenario where more people will eventually watch the TV online than they do on their traditional box in the living room. At this point, because of the paid for by advertising element, there would surely have to be a question mark over the future of the TV license fee.

Internet users are already beginning to be charged more for the increased usage that video online is stimulating. So effectively they are already paying twice though obviously these usage revenues don’t go to the BBC.
